[U-Boot] arch/powerpc/cpu/ppc4xx/start.S: comment makes little sense

[Wolfgang Denk <wd@denx.de>]

Dear Stefan,

I think this comment in arch/powerpc/cpu/ppc4xx/start.S needs a bit of
cleanup:

  51 /*  U-Boot - Startup Code for AMCC 4xx PowerPC based Embedded Boards
  52  *
  53  *
  54  *  The processor starts at 0xfffffffc and the code is executed
  55  *  from flash/rom.
  56  *  in memory, but as long we don't jump around before relocating.
  57  *  board_init lies at a quite high address and when the cpu has
  58  *  jumped there, everything is ok.
  59  *  This works because the cpu gives the FLASH (CS0) the whole
  60  *  address space at startup, and board_init lies as a echo of
  61  *  the flash somewhere up there in the memorymap.
  62  *
  63  *  board_init will change CS0 to be positioned at the correct
  64  *  address and (s)dram will be positioned at address 0
  65  */

All this makes pretty little sense to me.

Thanks.

Best regards,

Wolfgang Denk
